  2. General characteristics Body segmentation Endoskeleton Ventral heart Tail Pharyngeal pouches

  3. Adaptations

  4. Specific SpeciesDolioletta gegenbauri Kingdom:Animaila Habitat: tropical and temperate seas. Phylum:Chordata Class:Thaliacea Order:Doliolida Family:Doliolidae Genus:Dolioletta Species:Gegenbauri size:3-9mm even 15mm

  5. Distaplia cylindria Kingdom:Animalia Habitat: live on rocky bottoms. Phylum:Chordata Class:Ascidiacea Order:Aplousobranchia Family:Clavelinidae Genus:Distaplia Species:Cylindria size: 8.0cm

  6. Ciona intestinalis Kingdom:Animalia Phylum:Chordata Class:Ascidiacea Order:Phlebobranchia Family:Cionidae Genus:Ciona size:120 mm Species:Intestinalis Habitat: silty conditions.Most are found near rocky shores and estuaries

  7. Feeding • Feeding: They are filter feeders. They collect phytoplankton, and nutrient particles. • Water passes through the large gill basket, food particles are taken from the water and the endostyle secretes mucus to trap the food. • Then its passed to the dorsal midline of the pharynx where it is rolled into a mucus rope and passed to the stomach. • Passes to the intestine, and the faecal pellets formed go from the anus to the opening of the body to be released.

  8. Effect on Humans • Effect on Humans: Have a negative effect on fishing activities. They eat what fish feed on to survive which results on less fish for humans. • Problematic for marine aquaria keepers because they settle within the metal plumbing pipes and filters. • They have no positive effect on humans.

  9. Reproduction • hermaphroditic
